docker image —— x86 转 arm64

1.下载qemu
wget https://github.com/multiarch/qemu-user-static/releases/download/v5.1.0-2/qemu-aarch64-static.tar.gz
tar -zxvf qemu-aarch64-static.tar.gz -C /usr/bin/
2.启动qemu
docker run --rm --privileged multiarch/qemu-user-static:register
3.使用
例子
docker run --name C_ARM_MIDDLE  -id -v /usr/bin/qemu-aarch64-static:/usr/bin/qemu-aarch64-static -v /tmp:/tmp $ARM_BASIC  cp /tmp/ROOT.war /usr/local/tomcat/webapps

4.将x86架构的镜像，转换为arm64架构支持
